DESCRIPTION:
FEATURES:
The IDTQS74FCT2574is an8-bithigh-speedCMOSTTL-compatible
• CMOS power levels: <7.5mW static
• Undershoot clamp diodes on all outputs
• True TTL input and output compatibility
• Ground bounce controlled outputs
• Reduced output swing of 0 to 3.5V
• Built-in 25Ω series resistor outputs reduce reflection and other
system noise

removedfromthe device.
• Std., A and C speed grades with 5.2ns tPD for C
• IOL = 12mA
• Available in QSOP package
